Title: Improvements in or relating to vehicles with tipping bodies
IPC: B60P1/14
Filed: 1920-11-18
Abstract: 175,739. Thornycroft & Co., Ltd., J. I., and Barford, V. G. Nov. 18, 1920. Tipping-wagons.-In a vehicle having a body which can be tipped to either side at will, power for such tipping is transmitted from a single ram, screw, or equivalent at each end of the vehicle to a flexible or equivalent connector extending across the end of the body, the lifting effort being applied to the connector at ever varying points and being resisted at the-tipping side by the hinge axis about which the body tips. Each end of the body b is suspended by a flexible connector f which is attached to the lower edge thereof by pivotal connections g and passes over a pulley e on the head of a ram or screw a. Jaws k and pins n on the underside of the body detachably connect it to longitudinal rods j on the chassis, about which it can pivot. The pins n on one side of the body being removed, the pulley e can be raised to tip the body, the arrangement being such that the ram or the like always approximately bisects the angle made by the flexible connector f. In a modification, a rigid rail f<1>, Fig. 4, replaces the flexible connector.
